Description
Series Fans CFD Simulation using MRF Method, ANSYS Fluent Tutorial
In this project, steady air flow is investigated between two 3-bladed Series Fans CFD Simulation rotating at an angular velocity of 300 rpm using ANSYS Fluent software. We perform this CFD project and investigate it by CFD analysis.
The three-dimensional geometry of this project has been designed with spaceclaim software. The meshing of this project has been done with ANSYS Meshing software. The element number is 1914000.
Series Fans Methodology
In this project, steady air flow is investigated between two 3-bladed series fans rotating at an angular velocity of 300 rpm by ANSYS Fluent software. The rotation of fans generates air suction at the inlet boundary with a flow rate of 2.95755 m3/s.
The air velocity reaches values up to 25 m/s on the domain centerline; however, the maximum air velocity in the domain is equal to 47.05 m/s, which is captured downstream of the first fan. Moreover, the RNG k-epsilon model is enabled to solve turbulent fluid equations.
Series Fans Conclusion
At the end of the simulation, two- and three-dimensional contours related to pressure, velocity, velocity vectors, and streamlines are obtained. Also, based on Fluent’s calculated data, the air mass flow rate at the inlet equals 3.62019 kg/s.
A comparison between the pressure drops of the first and second fan shows that the pressure drops in the first fan have a higher value of 2 times more than the second fan. The pressure drop in the first and second fans equals 500 and 230 Pa, respectively.
Negative gauge pressure is observed downstream of both fans, where the pressure downstream of the first fan is five times less than the dual fan. Gauge pressure downstream of the first and second fan equals -500 and -100 Pa.
Based on the results obtained from the pressure drop values in both fans, the pressure drop in the first fan is higher, and the velocity magnitude downstream of the first fan has a higher value (28m/s) than the second fan (12m/s).

I noticed that the simulations use the MRF method. Can you explain why this method was chosen over others?
MR CFD Support –
The MRF (Multiple Reference Frame) method is a popular choice for simulating rotating machinery like fans. It simplifies the simulation by creating a stationary and a rotating zone, which makes it computationally efficient while still providing accurate results.
Roderick Romaguera –
How accurate are these simulations in predicting the actual performance of the fans?
MR CFD Support –
Our simulations are based on well-validated models and methods, such as the MRF method. While no simulation can perfectly replicate reality, they can provide a very close approximation and valuable insights into the performance of the fans.
Dr. Deborah Dicki IV –
Are there any limitations to these simulations?
MR CFD Support –
Like all simulations, ours have some limitations. For example, they assume steady-state conditions and use certain simplifications. However, they are still a powerful tool for predicting fan performance.
Abagail Ernser –
Everything in the tutorial seems really clear, but I just had one thing I’m wondering about: how is the rotating motion of the fans represented in the simulation? Is there a special method for that?
MR CFD Support –
In the simulation, the rotating motion of the fans is represented using the Multiple Reference Frame (MRF) method. This method involves treating the rotating fan blades as moving within their own rotating reference frame, which is then interfaced with the stationary reference frame of the surrounding air. This approach effectively captures the impact of the rotational movement without the need to physically animate the rotation of the fans.

Juana Beahan –
I’ve noticed from the series fans simulation conclusions, yet I’m curious about why the pressure drop in the first fan is higher than that in the second fan. Could it be due to the orientation or design of the fans?
MR CFD Support –
The greater pressure drop observed in the first fan compared to the second may result from the initial fan handling the majority of the pressure head gained from the airflow. As the air moves through the system, the first fan accelerates the flow, creating a high-pressure zone as the air is compressed and then a low-pressure zone as it is expelled and moves toward the second fan. By the time the air reaches the second fan, it has already been given kinetic energy, leading to a lower required pressure change to maintain the velocity developed by the first fan. Additionally, any system losses between fans could be a factor, as well as any slight differences in fan design or mounting that could impact performance.

America Bergstrom –
I was fascinated by the simultaneous coordination of two fans in the simulation. How does the MRF method enable the study of this dual fan system without involving actual fan rotation?
MR CFD Support –
The MRF (Multiple Reference Frame) method allows for the simulation of rotating machinery by defining stationary and rotating zones within the computational domain. The rotating zones in this case contain the fan blades, and they are set to rotate at the given angular velocity (300 rpm), while the bulk of the fluid domain remains stationary. MRF provides the effect of rotation and captures the flow features generated by the fan blades without the computational expense of physically rotating the mesh.

Prof. Morgan Kris –
I’m impressed by the level of detail provided in the velocity and pressure drop results. Could you provide insights on why the first fan experiences a higher pressure drop compared to the second?
MR CFD Support –
Thank you for the positive feedback! The higher pressure drop in the first fan can be attributed to its position in the airflow sequence. Being the first point of contact, it has to overcome the static pressure and initial resistance of the air mass, increasing the energy required to move the air. Consequently, it experiences a higher drop in pressure. As the second fan operates on air already in motion from the first fan, it encounters less resistance, leading to a lower pressure drop.
